PUMP.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed August 3, 1904:. Serial No. 219,383.

To all whom it may concern:

Be it known that I, SoLoMoN S. WHIPPS, a citizen of the United States,residing at Lesueur Center, in the county of Lesueur, State for itsobject to provide a pump for use in contracted space and in variousplaces where the operation of a bulky mechanism would be impracticable,the arrangement of the pump being such that it may be operated by meansof a cable connected with a source of power at a distance from the pump.

A further object is to provide a novel means for converting rotarymotion into reciprocating motion for operation of the pump.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that modifications of thespecific construction shown may be made, and any suitable materials maybe used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in whichlike characters of reference indicate similar parts in the severalviews, Figure 1 is a side elevation of the present pump connected withthe operating mechanism. Fig. 2 is a longitudinal section of Fig. 1.Fig. 3 is a top plan view of the driving mechanism. Fig. 4cv is asection on line 4 4 of Fig. 1. Fig. 5 is a side elevation of a portionof the mechanism employed in connection with a different form of pump.

Referring now to the drawings, the present invention comprises apump-cylinder 5, having the usual inlet and outlet valves 6 and 7 at itslower end and provided with a collar 8 at its upper end, from whichextend a plurality of upwardly-converging rods 9, having a guide-block10 secured to their upper ends.

Within the cylinder 5 there is disposed a piston 11, having a piston-rod12, which extends upwardly out of the cylinder and is engaged in theguide-block 10, and disposed between the piston and the guide-block andencircling the piston-rod 12 is a helical spring 13, which holds thepiston normally at the lower limit .of its motion.

The pump-operating mechanism consists of asupporting-frame 14,in whichthere is mounted in brackets 15 a slidable shaft 16, with the outer end17 of which the upper end of the piston-rod 12 is connected by means ofa cable 18. Secured to the frame M and extending at right angles to theshaft 16 is a circular yoke 19, which is spaced somewhat from the innerend of the shaft, and journaled in bearings 20 on this yoke is a shaft21, extending in a plane parallel to that occupied by the yoke andhaving a pinion 22 upon its inner end which lies above the inclosure ofthe yoke. Disposed within the yoke and extending beyond the upper andlower sides thereof is a' pitman 23, and pivoted at its upper end to theupper end of the pitman there is an elongated yoke 26, having aninwardly-extending flange 27 at its rearward edge. Extending from end toend of the yoke there is a plate which carries a plurality of forwardlyextending spaced pins 24:, these pins being connected at their outerends by a plate 25. The pinion 22 lies in engagementwith these pinsbetween the plates 25 and 25 and rests against the flange 27. Rotationof the shaft 21 results in reciprocation of the pitman, as will bereadily understood, the pins lying at opposite sides of the pinion 22during the upward and downward movement of the pitman. The pinion 22 isprovided with a cylindrical boss 28 upon one of its sides, against whichthe edges of the plate 25 rest as the yoke moves. Depending from thelower end of the yoke 26 is a plate 29, which extends transversely andwhich is provided with a slot 30, as shown, and lying in this slot is apin 31, carried by the pitman 23, and at either side of this pin thereextends from the pitman a wing 32,

these wings lying against the plate 29 to pre-- vent twisting of thepitman.

The pitman 23 is provided with a cylindrical extension 33, which ispivoted to a collar 34, slidably engaged with the shaft 16, and disposedbetween this collar and spaced flanges 35 upon the shaft, which lies ateither side of the collar, are helical springs 36, which surround theshaft 16. It will thus be apparent that rotation of the shaft 21 causesreciprocation of the pitman 23, as mentioned above, slight lateralmovement of the pitman being permitted by its pivotal connection withthe collar 3 1, this lateral movement being limited by the slot and thepin 31, as will be readily understood. Reciprocation of the pitman 23results in similar movement of the shaft 16, the springs 36 taking upall jar caused by the operation of the mechanism.

Movement of the shaft 16 in one direction causes outward movement of thepiston 11 and piston-rod 12, which compresses the spring 13, and thisspring returns the piston and piston-rods to their normal positions whenthe shaft 16 is moved in the opposite direction.

This pump is especially adapted for use in mines or in wells duringexcavating, as it may be readily moved from place to place, and, be ingdriven by mechanism disposed at a distance, may be successfully operatedin small space.

In Fig. 5 there is shown a construction in which the shaft 16 is omittedand the collar 34 is engaged with the piston-rod a of a plurality ofalining cylinders b, the spring 36 of the flanges 35 being provided, asdescribed above. This arrangement is especially adapted for citywaterworks, means for reciproeating the pitman 23 being capable ofproducing a large amount of power and the arrangement of the cylindersoccupying little space.

What-is claimed is 1. A pumping mechanism comprising a plurality ofcylinders, pistons disposed within the cylinders, a shaft slidablyengaged in the cylinders and connected with the pistons forreciprocation of the latter when the shaft is reciprocated, brackets inwhich the shaft is slidably engaged, collars carried by the shaft, apitman extending parallel to the shaft and having an eye in which theshaft is slidably end opposite to the eye, a plate extendinglongitudinally of the yoke centrally thereof, spaced rack-pins carriedby the plate, a powershaft disposed at one end within the inclosure ofthe yoke, a pinion carried by this powershaft and meshed with therack-pins, a plate carried by the yoke at its free end and having a slottherein extending transversely of the yoke, a pin carried by the pitmanand engaged in the slot for movement longitudinally thereof,andlaterally-extending wings carried by the pitman and resting againstthe plate to prevent twisting of the pitman with respect to the yoke.

2. The combination with a pump, of means connected therewith for oeration thereof, said means comprising a slidably-mounted rod, a pitmanpivotally connected with the rod, a yoke pivoted to the pitman aplurality of rackpins carried by the yoke, a revolubly-mountedpower-shaft, a pinion carried by the powershaft and meshing with thepins, a plate having an arc-shaped slot carried by the yoke, a pincarried by the pitman and engaged in the slot, and laterally-extendingwings carried by the pitman and lying against the slotted plate toprevent twisting of the pitman with respect to the yoke.

In testimony whereof I aflix my signature in presence of two witnesses.

SOLOMON S. WHIPPS.
